Objective:
Methamphetamine (METH) is a neurotoxic substance that can induce neurodegeneration in the human brain. Consequently chronic METH use can affect the cognitive functions in METH-dependent patients. In this study, we aimed to identify the relationship between cognitive function and brain-derived neurotrophic factor (BDNF), which reflects the status of neuroadaptive changes, by characterizing the effects on the cognitive function of METH-dependent patients.
Methods:
A total of 38 METH-dependent patients participated in this study. BDNF levels were measured using the enzyme-linked immunosorbent assay. We also examined the clinical features based on the measurements of the Consortium to Establish a Registry for Alzheimer’s Disease-Korean version (CERAD-K). Finally, the relationships between various parts of CERAD-K and BDNF were compared with one another.
Results:
METH-dependent patients were able to conduct most parts of CERAD-K stably. Among the parts of CERAD-K, only trail-making test part B was correlated with BDNF.
Conclusion
The trail-making test is specific for evaluating executive function; therefore, BDNF may play an essential role in detecting neurocognitive functional decline in METH dependence.

Objectives:
This study examined the factors associated with suicide risk among out-of-school youths (OSY) by analyzing their medical records retrospectively.
Methods:
The medical records of 280 OSYs who were admitted to the National Medical Center from January 2015 to December 2018 were examined. The demographic and clinical records, including behavioral problems, post-traumatic symptoms, harmful alcohol consumption, family functioning, and quality of life, were analyzed.
Results:
Among the 280 subjects, 80 (28.6%) were considered a high-risk suicidal group. The number of post-traumatic symptoms was found to be positively correlated, and the family functioning scores were negatively correlated with the increasing risk of suicide in the OSY based on the multiple regression analysis of the medical records.
Conclusion
The result of this study provides inputs for suicide prevention programs targeted at OSYs by identifying the risk and protective factors associated with suicide among the group.

This study examined the add-on efficacy of eye movement desensitization and reprocessing (EMDR) therapy among adult civilians with post-traumatic stress disorder (PTSD) who continued to be symptomatic after more than 12 weeks of initial antidepressant treatment. Scores for the Clinician Administered PTSD Scale (CAPS) were rated pre- and post-EMDR and at a 6-month follow-up. After an average of six sessions of EMDR treatment, seven of 14 patients (50%) showed more than a 30% decrease in CAPS score and eight (57%) no longer met the criteria for PTSD. Our results indicate that EMDR could be successfully added after failure of initial pharmacotherapy for PTSD.

PURPOSE: Traumatic events and adverse stressful experiences are major etiological factors in a wide variety of physical and mental disorders. Developing psychological instruments that can be easily administered and that have good psychometric properties have become an integral part for research and practice. This study investigated the reliability and validity of the Korean version of the Lifetime Stressor Checklist-Revised (LSC-R) in a consecutive sample of psychiatric outpatients. The LSC-R is a 30-item self-reporting questionnaire examining lifetime traumatic and non-traumatic stressors. MATERIALS AND METHODS: A final sample of 258 outpatients with anxiety or depressive disorders was recruited at the psychiatric department of a university-affiliated teaching hospital. Self-reported data included the Life Events Checklist (LEC), the Zung Self-Rating Depression and Anxiety Scales, and the Impact of Events Scale-Revised, in addition to the LSC-R. A convenience sample of 50 college students completed the LSC-R on two occasions separated by a three week-interval for test-retest reliability. RESULTS: Mean kappa for temporal stability was high (κ=0.651) and Cronbach alpha was moderate (α=0.724). Convergent validity was excellent with corresponding items on the LEC. Concurrent validity was good for symptoms of post-traumatic stress disorder, depression, and anxiety. An exploratory factor analysis revealed that 11 factors explained 64.3 % of the total variance. CONCLUSION: This study demonstrated good psychometric properties of the Korean version of the LSC-R, further supporting its use in clinical research and practice with a Korean speaking population.

OBJECTIVE: The ratio of 2nd to 4th digit length (2D:4D) is a sexually dimorphic trait. Men have a relatively shorter second digit than fourth digit. This ratio is thought to be influenced by higher prenatal testosterone level or greater sensitivity to androgen. The purpose of this study is to investigate the relationship between alcohol dependence and 2D:4D in a Korean sample and whether 2D:4D can be a biologic marker in alcohol dependence. METHODS: In this study, we recruited 87 male patients with alcohol dependence from the alcohol center of one psychiatric hospital and 52 healthy male volunteers who were all employees in the same hospital as controls. We captured images of the right and left hands of patients and controls using a scanner and extracted data with a graphics program. We measured the 2D:4D of each hand and compared the alcohol dependence group with the control group. We analyzed these ratios using an independent-samples t-test. RESULTS: The mean 2D:4D of patients was 0.934 (right hand) and 0.942 (left hand), while the mean 2D:4D of controls was 0.956 (right hand) and 0.958 (left hand). Values for both hands were significantly lower for patients than controls (p<0.001, right hand; p=0.004, left hand). CONCLUSION: Patients who are alcohol dependent have a significantly lower 2D:4D than controls, similar to the results of previous studies, which suggest that a higher prenatal testosterone level in the gonadal period is related to alcoholism. Furthermore, 2D:4D is a possible predictive marker of alcohol dependence.

The Symptom Checklist - Post-Traumatic Stress Disorder Scale (SCL-PTSD), also known as Crime-Related PTSD Scale has been validated in survivors of interpersonal trauma in the general population. However, the psychometric properties have not been investigated in a clinical setting for patients with PTSD from diverse traumatic events. This study investigates the reliability and validity of the Korean version of the SCL-PTSD among 104 psychiatric outpatients with PTSD, caused by interpersonal (n = 50) or non-interpersonal trauma (n = 54). Self-report data of the SCL-PTSD, Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Impact of Events Scale-Revised (IES-R) were gathered. The Korean version of the SCL-PTSD showed excellent internal consistency and moderate-to-good four-week temporal stability in both the interpersonal and non-interpersonal trauma groups. In comparison with other diagnostic groups, the scores of the SCL-PTSD were significantly higher compared to those of adjustment disorder, depression, other anxiety disorders, and schizophrenia, demonstrating its criteria-related validity. Convergent validity was confirmed because the scores of the SCL-PTSD were significantly correlated with BDI, SAI and TAI scores. Concurrent validity was demonstrated by significant correlation with the IES-R score. This study demonstrated the favorable psychometric prosperities of the Korean version of the SCL-PTSD, supporting its use in clinical research and practice.
